Step 13: The critical twist

Picture of The critical twist
After the loop-the-loop, we are set to complete the intricate twist of the strip that is necessary for producing the correct type of three-dimensional star point.

For stars that have the same handedness as the one showed in the pictures, The tip of the strip should now be rotated three quarters of a turn counter clockwise. The axis of rotation is orthogonal to the base knot plane.

Or, inspired by the loop-the-loop terminology, after the stunt aircraft has made its loop-the-loop, it should stop dead, turn into a helicopter, then turn 270 degrees to the left.

Hopefully, the many pictures taken from different angles will help you stay on track.
